Microsoft Volume Shadow Copy (VSS) Integration

This release introduces Cache and Ensemble integration with Microsoft's Volume Shadow Copy Service (VSS) framework. This integration allows any backup product which supports VSS integration to identify databases and the volumes they reside on and seamlessly quiesce Cache and Ensemble instances when performing a backup of the system. The copies of the databases included in a VSS shadow are physically, although not logically with regards to transactions, consistent and therefore may be restored individually. To ensure the transaction integrity of these restored databases, one should also replay journal files accordingly.
